Description :
Were looking for an accomplished Firmware Engineer with 8+ years of experience in developing and optimizing embedded audio software for Bluetooth-based and low-power systems. Youll play a key role in building the audio intelligence that powers our next-generation AR / VR smart glasses and immersive hardware.
Role Overview :
As part of our cross-functional hardwaresoftware engineering team, youll design, implement, and refine embedded firmware that directly influences the acoustic performance, power efficiency, and user experience of our wearable products.
Key Responsibilities :
- Design and enhance embedded audio firmware in C / C++, with a focus on real-time processing, low-latency performance, and energy efficiency.
- Implement and optimize Bluetooth Classic and BLE audio protocols (A2DP, AVRCP, HFP, HAP, TMAP, HAS, PBP).
- Integrate and tune audio codecs such as SBC, AAC, aptX, and LC3.
- Work with hardware teams to integrate and validate audio peripherals microphones, amplifiers, speakers, etc. over interfaces like I2S, UART, and SPI.
- Contribute to DSP optimizations, ANC / ENC algorithms, and real-time audio streaming pipelines.
Technical Expertise Required :
Expert in Embedded C / C++ and real-time programming on constrained devices.Strong grasp of Bluetooth architecture, audio profiles, and advanced positioning techniques(AoA / AoD).
Deep knowledge of noise reduction and audio enhancement techniques.Experience in debugging, profiling, and system optimization for embedded platforms.Preferred Experience :
Exposure to RTOS or Embedded Linux environments.Hands-on experience with Qualcomm CSR, Nordic nRF52, or Broadcom Bluetooth stacks.Understanding of audio streaming, latency optimization, and buffer management.Familiarity with Agile practices, Git-based workflows, and CI / CD pipelines.Bonus Skills :
Use of Ellisys, Frontline, or similar tools for Bluetooth packet analysis.Experience in audio quality measurement (latency, jitter, fidelity).Low-power design experience for wearable or portable devices.Other Details : timeline : Within 20 days
